The first ingredient in this dog food is salmon meal. Salmon meal is considered a meat concentrate and contains nearly 300% more protein than even fresh salmon.
We are pleased to note that, unlike many fish meals, this particular item appears1 to be ethoxyquin-free.
The second ingredient lists potato flakes… a dehydrated potato product usually made from by-products of a food processing plant. This item is equal to corn in calorie content yet with notably more protein.
The third ingredient is tapioca. Tapioca is a natural extract made from the root of the cassava plant. It is a starchy carbohydrate that is not only grain-free… but also gluten-free.
The fourth ingredient is field peas. Peas are a quality source of carbohydrates. Plus (like all legumes) they’re rich in natural fiber.
However, peas contain about 25% protein… a factor that must be considered when evaluating the total protein reported in this food.
The fifth ingredient lists canola oil. Most applaud canola for its favorable omega-3 content… while a vocal minority condemn it as an unhealthy fat.
Current thinking (ours included) finds the negative stories about canola oil more the stuff of urban legend than actual science.2
However, plant-based oils (like canola) are less biologically available to a dog than fish oil as a source of quality omega-3 fats.
The next ingredients include catfish and herring meals… two more protein rich meat concentrates.
Again, the company has assured us all fish meals used to make this product are ethoxyquin free at the time they are procured.3 to be ethoxyquin-free.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.
With three notable exceptions…
First, this recipe contains fructooligosaccharide… an alternative sweetener4 probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.
Next, the company appears to have applied friendly microorganisms to the surface of the kibble after cooking. These special probiotics are used to enhance a dog’s digestive and immune functions.
And lastly, this food also contains chelated minerals… minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Blackwood Special Diet Dog Food
The Bottom Line
Judging by its ingredients alone, Blackwood Special Diet dog food looks to be an above-average kibble.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
The dashboard displays a dry matter protein reading of 31%, a fat level of 17% and estimated carbohydrates of about 44%.
As a group, the brand features an average protein content of 29% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 47% for the overall product line.
Average protein. Average fat. And average carbs when compared to a typical dry dog food.
In addition, when you consider the protein-boosting effect of the field peas, this looks like the profile of a kibble containing a moderate amount of meat.
Bottom line?
Blackwood Special Diet Dog Food is a plant-based kibble using a moderate amount of poultry and fish meals as its main sources of animal protein… thus earning the brand 4.5 stars.
Highly recommended.
